Title: Liggard Brook and Main Drain improvement scheme
Author: Environment Agency North West Region
Document Type: Monograph
Flooding of Lytham and die surrounding farmland has been a problem for many years. The area is flat and low lying and is drained by two watercourses, Liggard Brook and Main Drain. These watercourses discharge into the Ribble Estuary through tidal outfalls. Twice a day, at high tide, the outfalls are tidelocked as sea levels are higher than the water levels in the in-land waterways. This means that water cannot pass from the land out to sea and when this occurs together with heavy rainfall, flooding is the inevitable result. The excess water cannot be completely drained between successive tides, and water levels remain high for several days. Liggard Brook passes through the centre of Lytham and receives water from numerous surface water drains. Following heavy rainfall, high water levels in Liggard Brook prevent the efficient operation of these drains, causing flooding of property and water logging of the surrounding area. In all, more than 100 houses are affected. Main Drain and the upstream lengths of Liggard Brook drain the farmland around Lytham. Some flooding of farmland is experienced every winter. In all more than 600 hectares are at risk of flooding.
